Selling a Flat With Service Charge Arrears: 2026 UK Guide

By Lisa Hayes · 26 September 2026

Yes, you can sell a leasehold flat with service charge arrears outstanding — but almost nothing moves until they're either cleared or your solicitor gives a written undertaking to pay them from the sale proceeds at completion. Skip that step and you'll find your freeholder or managing agent simply won't answer your buyer's pre-sale questions, which stalls the whole chain, sometimes for months.

I see this constantly with flat sales that have gone quiet for no obvious reason: the buyer's solicitor sent a perfectly ordinary enquiry weeks ago, and nobody at the management company has replied. Nine times out of ten, there's an unpaid balance sitting on the account that nobody's mentioned to the person actually trying to sell. Let's get you ahead of it.

What actually counts as service charge arrears?

Service charge arrears are simply any amount your freeholder or managing agent has formally demanded — for buildings insurance, communal repairs, cleaning, a reserve fund contribution, or your share of a Section 20 major works bill — that you haven't paid by the due date. They build up quietly. A missed quarterly invoice while you were dealing with something else, a disputed charge you never resolved, a balancing charge from a year-end reconciliation you didn't know was coming. None of it needs to be dramatic to become a real problem the moment you try to sell.

The important distinction is between charges that are demanded and unpaid versus charges you simply disagree with. Both show up on the management pack your buyer's solicitor requests, and both need addressing before completion — just through different routes, which I'll come to.

Worth saying plainly: arrears are more common than the silence around them suggests. Leaseholders often don't realise a charge has gone unpaid until they're mid-sale, especially where invoices go to an address they've since moved from, or where a standing order set up years ago quietly stopped covering an increased annual charge. It's rarely negligence. It's usually just a paper trail nobody was watching, which is exactly why checking your account status the day you decide to sell — rather than waiting for your buyer's solicitor to find it for you — puts you back in control of the timeline instead of reacting to it.

What is the LPE1 form, and why won't anything move without it?

The LPE1 — the Leasehold Property Enquiry form, sometimes bundled into what's called a management pack or seller's information pack — is what your buyer's solicitor sends to your freeholder or managing agent early in the transaction. It asks for three years of service charge accounts, the current year's budget, buildings insurance details, ground rent payment history, any Section 20 consultation notices, reserve fund information, and confirmation of whether any charges are outstanding.

Here's the bit that surprises most sellers: your freeholder has no legal obligation to respond to it at all. Most do, because it's normal practice and nobody wants a reputation for obstruction — but if you owe arrears, plenty of managing agents will deliberately sit on that LPE1 response until the money question is resolved, precisely because answering it can be read as accepting the sale and waiving their right to chase you for the debt later. That's not bad customer service. It's a fairly standard legal tactic, and it's exactly why arrears need sorting at the start of your sale, not somewhere in the middle when your buyer's patience is already running thin.

How much does the management pack cost, and how long does it actually take?

Budget £200 to £500 plus VAT. The Law Society has suggested £200 plus VAT as a reasonable figure for the LPE1 itself, though larger developments, block-wide reserve fund calculations, or a managing agent that charges for expedited turnaround can push that higher.

• Fast agent ~12 days
• Average agent ~21 days
• Slow agent / self-managed freeholder ~42 days

Order it the day you decide to sell — before you've even chosen an estate agent, ideally. Most delays in a leasehold sale trace back to this single document arriving late, and it takes exactly as long whether or not you have arrears. If you do have arrears, it takes longer still, because the agent will often wait for the money conversation to conclude before releasing anything.

Will the arrears just come out of my sale proceeds automatically?

Not automatically, but this is usually how it gets resolved in practice. Once your solicitor knows the figure — either because you've settled it directly or because the freeholder has confirmed the amount owed — they'll typically arrange one of two things: full payment from your side before completion, or a retention, where a specific sum is held back from your proceeds at completion and paid across once the final balancing figures are confirmed. Retentions are especially common where there's a live service charge year that hasn't been reconciled yet, because nobody knows the exact final number until the accounts are done.

This is also where balancing charges catch people out. If your service charge year ends after you've completed and moved out, a bill covering part of your period of ownership can still land — which is exactly why your conveyancer should be asking the managing agent for a forecast, not just the historic accounts, before agreeing any retention figure.

Does my buyer inherit my arrears if I don't sort them out?

No — and this is one of the most persistent myths in leasehold selling. Only the leaseholder who owned the flat when a charge was demanded is liable for it. If a bill lands the week before completion and you haven't paid it, that liability doesn't automatically transfer to whoever buys the flat from you. Your buyer's solicitor knows this, which is precisely why they'll refuse to let the sale complete with unresolved arrears sitting on the account rather than simply accepting them as the new owner's problem.

What can follow the property, in a different sense, is the freeholder's right to chase the debt against the lease itself if the sale isn't handled correctly — which brings us to the part that actually matters if you're trying to move on and leave the whole mess behind you.

Can my freeholder actually forfeit the lease while I'm trying to sell?

Not on a whim, and not just because money is owed. A landlord cannot serve what's called a Section 146 notice — the formal first step toward forfeiture — unless you've admitted the breach yourself, or a court or the First-tier Tribunal has already determined that you owe the money and haven't paid. That's a meaningful legal hurdle, not a rubber stamp, and it's worth knowing so you don't panic into paying a disputed sum you don't actually owe just because forfeiture was mentioned in a letter.

That said, don't treat this protection as a reason to ignore the problem. A tribunal determination against you is still entirely possible if the charges are properly demanded and genuinely due, and once that determination exists, the forfeiture clock starts. The safer, faster route is almost always to resolve what's owed — or formally dispute what you think is wrong — well before your buyer's solicitor even sends the LPE1 request.

Should I dispute charges I think are unfair, or just pay and sell?

If you genuinely believe a charge is wrong — unreasonable major works costs, a service you're being billed for but never received, an unexplained jump in the budget — you can challenge it at the First-tier Tribunal (Property Chamber). That's your right, and it exists for a reason. But be honest with yourself about timing: a tribunal application takes months to resolve, and your sale won't wait for it.

For most sellers who are prioritising a move rather than a principle, the pragmatic path is to pay under protest — settling the amount to keep your sale moving, while keeping every piece of correspondence that shows you disputed it — and pursuing reimbursement afterwards if you're proven right. It's not always satisfying, but it keeps a buyer at the table instead of watching them walk away while you make a point.

Is a cash buyer or quick-sale route realistic if I've got arrears outstanding?

Often, yes — and for exactly the reasons that make a mortgaged buyer's transaction so fragile here. A high street lender's underwriters will frequently refuse to release funds while an LPE1 shows unresolved arrears, a live dispute, or an unreconciled service charge year, because they don't want to lend against a flat that might carry a forfeiture risk. That's precisely the kind of thing that causes mortgaged sales to collapse three or four months into a chain, after your buyer has already paid for surveys and searches.

A cash buyer isn't relying on a mortgage offer, so they're not exposed to that particular objection in the same way — though a reputable one will still want the arrears figure confirmed and a retention or clean settlement agreed before completion, because they'll want to own a flat that isn't carrying a forfeiture risk either. If speed matters more to you than squeezing the last few thousand pounds out of an open-market sale, it's worth comparing more than one buyer rather than assuming a mortgaged sale is your only realistic option. Our guide to the best house-buying companies is a sensible starting point if you're weighing this up, and a genuine cash house buyer can often complete in weeks rather than the months a complicated leasehold chain can drag on for.

How does having arrears change the overall sale timeline?

A straightforward leasehold sale runs to roughly 12 weeks from a sensible open-market process, with completion typically 7 to 28 days after exchange once everyone's agreed terms. Arrears don't necessarily add huge amounts of time by themselves, but they add uncertainty at precisely the stage — post-offer, pre-exchange — where buyers get twitchy and start looking at other properties. A management pack that arrives late because the agent's waiting on a payment conversation, followed by a retention negotiation your solicitor has to run from scratch, can easily turn a 12-week sale into a 20-week one.

If you're already selling because the flat feels like it's become genuinely hard to shift — arrears, an unresponsive freeholder, or both — it's worth reading our broader guide on selling a difficult or unsellable property, since a lot of the same principles about managing buyer expectations and choosing the right route apply.

What about my freeholder simply not responding at all?

Arrears aside, some freeholders are just slow, uncontactable, or effectively absent — which is its own specific problem with its own fix. If chasing a response feels less like "waiting for arrears to clear" and more like shouting into a void, our dedicated guide on selling a flat with an absent freeholder covers the specific legal routes available, including applying to be recognised as your own manager under the right to manage provisions.

What if a big Section 20 bill caused the arrears in the first place?

This is one of the most common routes into arrears, and it's rarely the leaseholder's fault in any meaningful sense. A block needs a new roof, external redecoration, or lift replacement; the freeholder issues a Section 20 notice consulting leaseholders on the works; the bill lands at £8,000, £15,000, sometimes far more, apportioned according to your lease. If you couldn't pay it in one go and didn't arrange a payment plan with the managing agent quickly, it sits as an arrear on your account from that point on, quietly accruing alongside whatever else is due.

The practical fix, if you're selling into this situation, is the same principle as everywhere else in this guide: get the figure confirmed in writing, work out whether it's fully paid, part-paid, or disputed, and make sure your solicitor knows the real number before your buyer's LPE1 request goes anywhere near the managing agent. A partially-paid major works bill is exactly the kind of thing that turns into a lengthy retention negotiation if it's discovered late rather than disclosed upfront. If major works are a recurring theme for your block rather than a one-off, it's also worth checking whether ongoing estate management charges are part of the picture — sometimes labelled "fleecehold" charges — since those work slightly differently from a standard service charge and are worth understanding on their own terms before you agree to any repayment figure.

What if I inherited the flat and the arrears predate me?

This comes up more often than you'd think, and it's genuinely one of the more stressful versions of this problem: you inherit a leasehold flat, only to discover through the LPE1 process — sometimes not until you're already trying to sell it — that the previous owner left arrears on the account. As executor or beneficiary, you're generally dealing with a debt that technically belongs to the estate rather than to you personally, but in practice it still needs resolving from the estate's funds, or via the sale proceeds, before the freeholder will cooperate with your buyer's solicitor.

The sequence doesn't really change: get the exact figure in writing from the managing agent, establish whether it's genuinely owed or worth disputing, and make sure whoever's handling the estate's legal affairs flags it to your buyer's solicitor early rather than letting it surface as a surprise. If you're navigating this alongside probate itself, our guide on selling an inherited property covers the wider process, and it's worth reading alongside this one rather than treating the arrears as a separate problem from the inheritance itself.

What mistakes actually make this worse?

Three patterns show up again and again in stalled leasehold sales with an arrears problem sitting underneath them:

• Not ordering the management pack until a buyer's already found. By the time it arrives weeks later, your buyer's patience — and sometimes their mortgage offer — has already expired.
• Assuming a verbal "I'll sort it" is enough. Freeholders and their solicitors work on written undertakings, not promises. Get your solicitor to put it in writing early.
• Ignoring a demand you think is wrong instead of formally disputing it. Silence doesn't count as a dispute. If you're not going to pay, tell them in writing why, and keep every letter.

None of this is complicated once you know the sequence. It only becomes a crisis when it's discovered halfway through a sale instead of planned for at the start of one.

What if the flat's already been sitting unsold for months because of this?

By the time most people go looking for answers on service charge arrears, they're not asking in the abstract — they're three months into a sale that's gone quiet, or they've had a buyer pull out already after their solicitor raised the LPE1 delay as a reason to walk. If that's where you are, the calculation changes slightly. It's no longer just about getting the paperwork right; it's about deciding whether to fix the arrears and relist through the open market, or accept that speed and certainty matter more than chasing the highest possible price from a buyer who might disappear again in another three months.

There's no universally right answer here — it depends on how much equity you have, how urgently you need to move, and how patient you can afford to be. But if you're weighing it up, it's worth reading our guide on selling a flat fast alongside this one, because a lot of the buyer-comparison advice there applies directly once arrears have already cost you one sale and you'd rather not risk a second.

Where does the general leasehold sale process fit around all this?

Everything above sits on top of the ordinary mechanics of selling a flat with a lease — you'll still need to think about the length of lease remaining, ground rent, ownership of the freehold or share of freehold, and buildings insurance arrangements alongside the arrears question specifically. Our full walkthrough of how to sell a leasehold flat covers that wider process end to end, and if any of the terminology here — retention, undertaking, forfeiture, LPE1 — is new to you, our property jargon explained guide translates the rest of the paperwork you'll be handed along the way. And once you've exchanged and are counting down to your actual moving date, what happens on completion day walks through exactly how the money — including any retention — actually moves.
